a valve. The handle in the patented structure Vmay accidently press against the ground y or against some object so as to cause it to unseat the valve atan inopportuno time so liquid liow will be permitted when it is not desired.

cally cutting olf the My present invention contemplates a structure in which it will be impossible to accidently unseat the valve and to this end it comprehends a manually controlled means independent of the operating mechanism for rendering the valve-unseating mechanism" functional only so long as the means just mentioned is held in functional position but there is means also rovided for automatiow of liquid when the lever in the tank or receptacle reaches .a predetermined level or becomes full.

. The novel construction by means of which the desired result is accomplished will be clearly understood by reference to the following description in connection with the accompanying drawings in which:

Figure 1 is a vertical longitudinal sectional view of a filler spout constructed in accordance with my invention, part of the nozzle being removed. l

Figure 2 is a fragmentary perspective view of the positively actuated operating mechanism, and ,f

Figure 3 is a of the nozzle. Y

1 designates the tubular end of the filler spout to which thehose from the source of supply is attached. 2 designates alnozzle connected to the tubular member by anfintermediate housing or casing 3 in which may be located the valve operating and controlling mechanism which includes the novelty of my invention. f

At the juncture of the tubular member wlth the housing is a valve seat 4 having a forfragmentary sectional view wardly directed valve stemguide in which is a valve stem 6 having a,` valve 7 at one end and a fixed collar 8 at the other. A coll s rmg 9 surrounds the guide one end of which ears against the collar 8 tending to keep the valve seated to close olf the iow of liquid.

The .end of the stem distant from the valve 7 is pivoted to a connecter 10 having a slotA 11 in which the extremity of the stem 6 is received'and pivoted at 12. A link 13 is pivoted to the connecter or bar `10 at 14 and it is also pivoted to a finger 15 at16, the inger 15 being fast t'o a shaft 17 mounted in the' casing and having at least one end projecting through the casing to support a hand lever 18 extending to the tubular portion ;l so that it can be easily grasped by the hand of the operator. The connecter 10 and the link 13 constitute a break joint which is normally Y held in functional position rby the spring 19 coiled at its center about the pivot 14 which connects the link 13 to the connecter 10, the ends of the spring bearing against the pivots 12 and 16. It should be here noted that the pivot 14 should be slightly offset below the pivots 12 and 16 so as to most eliiciently hold the parts 6, 10 and 16 in the functional posi'- tions shown in the drawings so that when the handle 21 is pressed downward the shaft 17 will be rocked to swing the finger 15 to force Ithe valve off its seat. i

Normally the break joint is held out of functional position to operate the valve 7 by the pin 22 in guide 23 carried'by the case 3. The pin 22 is pivoted to the end 24 of the lever 25 fulcrumed to the lug 26 and normally pressed outwardly by the expansion spring 27 bearing against the housing 3 and the lever 25. Slincethe spring is on that side of the fulcrum vdistant from the pin, it will be apparent that Ithe normal tendency will be for the spring to force the handle 25 out and the pin 22 in so as to exert a push against the plate 28 integral with connector 10 to force the pivot 14 above the pivots 12 and 16 and while the parts are in this position the joint will be broken or rendered non-functional to lunseat the valve 7 so that even when the handle 21 is pressed in the valve 7 will not be unseated unless the handle 29 on lever 25 is at the same time pressed 1n to wlthdraw the pin .22 from engagement with the break- I spring 27 to urgepin 22 upwardly to contactI with the joint consisting of the levers 11 and 12 so that the lever 18 will not be effective to open the valve 7. When, however, the handle 29 is moved toward the member 1 to compress the spring 27, thespring 19 will cause the links of the joint to alineso that the lever 18 may become effective to unseat the valve 7.

There is another feature of importance 1n this device which is generically disclosed in my former patent but slightly modified to suit this latest form of. my invention.

The feature just referred to is the provision of automatic means to cause the valve 7 to seat when the liquid in the receptacle being filled, reaches a predetermined level which is generally when the tank is full.

rlhe automatic cutoif includes a sealed diaphragm chamber 30 having a rigid wall 31 and a flexible wall or diaphragm 82, the cha1n. ber having an opening 34 communicating with a tube 35' passing through the wall o f a Venturi tube 36 in the nozzle 2,"terminat1ng at the discharge end of the nozzle.

The diaphragm 32 carries a stud 37 pivoted to a lever 38 fulcrunied on the stud 39, carrying at its free end a link 40 engaging the slot 41 in the plate` 28.

The automatic cutoffy operates as follows: When the li uid is flowing through the nozzle and particu arly through the Venturi tube the velocity of the liquid will tend to exhuast the air out of the chamber 3 0l through opening 42 but since the lower end 43 of the pipe is open to atmosphere maintaining a conlstant atmospheric pressure at the inlet end 43 o f pipe 42, air will be drawn up vthrough end 43 to outlet opening 42 this being the easier path forthe air to travel because when' the pressure in the chamber 30 drops slightly be- V- low atmospheric pressure there will be a tendency 'to reestablish the pressure in Said chamber, while a drop in pressure at the outlet 42 will cause air to rush into the tube 35 through the -inlet 43. When, however, the lower end 43 of the pipe 35 is submerged the end 43 will-.bre thus sealed,` it' will then be easier to exhaust air from chamber 30 than to lift the liquid in pipe 35. As a result, a partial vacuum will be established in chamber'30 so that a down pull will be exerted yupon the stud 37 and an up pullon the rod 40 to swing the connectorllO about the pivot 12 :This will raise they pivot 14 in a. plaiie above pivots 12 and 16. The relatively strong spring 9 may now become effective to sna'p the valve 7 upon its seat by causingthe break joint to buckle.

This latteraction will take place even when the two handles 21 and 29" are rclose'to the tubular portion '1, consequently thevalve will be automatically/seated wheneverwthe discharge end ofthe nozzle Ais submerged and the liquid is flowing from the sourceA of su y. j

rom the foregoing it will be seen Athat danger of accidental undesirable unseatingv of the valve will be entirely prevented and closing of the valve will be assured when the predetermined level in the receptacle has been reached.
